EVER heard the term across-ventilationa mentioned in a real estate ad or a story about a million-dollar architect-designed place and thought it sounded like scientific mumbo jumbo?

That's the trouble with architect-speak sometimes or techno talk of any kind a what is a relatively simple concept can suddenly look awfully complicated.

But anyone who has ever gone camping will be able to tell you the basics of cross-ventilation a opening up opposite windows (or tent flaps) to allow the air to flow from one side to another.

Mr Rosen said rather than having windows directly opposite each other, it can be helpful to have them offset somewhat.
